As hard as it is to do people like him just need to be ignored, he is obviously pushing you around to compensate for his own shortcomings so just be content knowing you are not an ahole. He will leave school and try it on with someone who will put him in his place eventually but you will be long gone well on your way and won't have to worry.

The next time he tells you to move something ask him if his arms are painted on, if not move it himself the lazy git!
